The BIOS will *not* control add-on hardware. The BIOS has firmware
code blocks for chips which are actually soldered to the motherboard.

If you plug a USB Bluetooth nano receiver into a USB port,
it doesn't have a driver for that. The Bluetooth nano receiver
(like a Logitech Unifying receiver) can present a USB HID
interface. That means the radio portion is not exposed at
all, and all the BIOS can see is a USB wireless keyboard

Actually, I think a USB keyboard, not a USB wireless keyboard (-:

The combination of a USB wireless (Unifying/nano) receiver with HID interface
on the USB side, plus a wireless keyboard (operating at 2.5GHz).
